Summary0010464: vtkSeedWidget CRASH!!!
DescriptionThe method DeleteSeed of the class vtkSeedWidget crash:

void vtkSeedWidget::DeleteSeed(int i)
{
  if( this->Seeds->size() <= static_cast< size_t >(i) )
    {
    return;
    }

  vtkSeedRepresentation *rep =
      static_cast<vtkSeedRepresentation*>(this->WidgetRep);
  if (rep)
    {
    rep->RemoveHandle( i );
    }

  vtkSeedListIterator iter = this->Seeds->begin();
  vtkstd::advance(iter,i);
  (*iter)->SetEnabled(0);
  (*iter)->RemoveObservers(vtkCommand::StartInteractionEvent);
  (*iter)->RemoveObservers(vtkCommand::InteractionEvent);
  (*iter)->RemoveObservers(vtkCommand::EndInteractionEvent);
  vtkHandleWidget * w = (*iter);
  this->Seeds->erase( iter );
  w->Delete();
}

The problem is in the last two lines. You have to FIRST delete the object, then erase the relative iterator. That is you have to swap the last two lines:

  w->Delete();
  this->Seeds->erase( iter );

Please fix it! Thanks.

 I cannot reproduce the problem. Probably isn't a bug. I'm sorry.
